When I crank the engine no negative trigger on the ignition coil the same with the fuel injectors. No negative trigger on the fuel pump relay but the live and ignition power is ok. Replaced CKP sensor, ignition coil still not run. Checked all fuses found all good. ECU been removed and put on to another car it starts and run.

Connector, conductor, component is the path I follow when investigating what seems like a wiring issue. There are several sites for the wiring diagrams you will need. Has the main relay been replaced with the correct relay?
